BROOKE FINISHING BEADING, MOLDING AND THE LIKE FiledFeb. 1'?, 19321 Patented Sept. 3, 1935 FINISHING BEADING, HOLDING, ANDTHE LIKE Alec Brooke, Coventry, England Application February 17, 1934,Serial No. '111,762 In Great Britain May 23, 1933 Claims. (Cl, 155-184)depth of the material to which the attachmentl is to be made isinsufficient-to aiord a secure hold ,10 for ordinary nails. Such casesoccur where the substructure of the article to which the attachment hasto be made is of metal covered with a thin layer of wood or the like.

The invention consists in the combination or association with headings,edgings, moldings and the like finishings for the purposes described, ofa series of attachment means permanently secured thereto and consistingof short` prongs adapted to spread apart when driven home. By reason oftheir form and action when driven home these means can be made muchshorter than the usual nails and yet provide a convenient and secureanchorage for the finishing or molding. In the accompanying drawing,

Figure 1 is explanatory of one of the difficulties which are at presentexperienced in attaching finishings and moldings of the kind hereinreferred to by means of ordinary nails.

Where, as represented in Figure 1, it is required to secure a beading ormolding a. around a sharp 10 bend by means of ordinary nails b of therequisite length, it will at once be obvious that the operation isattended with considerable difficulty. Even where the beading is of aflexible nature it is by no means an easy thing to fix it at the 15corner so that it lies uniformly and is at the same time secure. Thedifilculty is considerably greater when the molding is made of a ductilemetal, for if the nail b is bent so as to be presented at right anglesto the surface c the result is to cause the molding to form a, hump atthe corner, whereas if an attempt is made to drive the same nail bobliquely into the surface c it either lies flat and does not enter atall or it takes a very insecure hold, with the result that there isalways a tend- 25 ency for the molding to gape at the corner.

These difiiculties are entirely avoided and a firm and durableattachment readily made by the adoption of attachment devices of thekind hereinafter described which are permanently se- 30 cured to themolding or beading.

In the form shown in Figures 2 and 3 the improved attachment devicesconsist of lshort T- shape driven means formed with short bifurcatedShanks and having a spread head, and xed at 35 intervals to a metalstripv e embedded in the beading a. Owing to the increased securitywhich is afforded by the spreading and clinching of their furcations theShanks of these fastening devices or means need not extend more than laquarter 40 of an inch from or beyond the face of the beading in whichthey are embedded and consequently the attachment of the beading therebyis rendered a comparatively simple matter whatever may be the contour ofthe surface to which it is to be applied. These bifurcated fasteningmeans kcan either be made separately and welded, or otherwise secured tothe strip e, or, they may be made as integral parts of the metal stripz' by forming them opposite each other along the edges of 5o the strip,bending them at right angles to the latter and then twisting them abouteach other as lshown in Fig. 'I so as to form a bifurcated shank havingfurcations f that will spread apart below the twist when driven home. 55

60 therewith y Where the fastening means are formed `inl According tothe preferred embodiment the individual fastening or securing means ismade Aof a piece of preferably flat thin stiff metal wire folded uponitself into T form, the head constituting a flattened loop with the twoend portions depending in close proximity from the central portion ofthehead to form a bifurcated shank havingprongs or furcations ,f which arepreferably of substantially equal length and have their adjacentlower'end edges beveled downwardly and outwardly away from each other asat f', Aas shown in Figures 2 and 4, so that when driven into a supportor foundation the material of the latter will initially enter betweensaid beveled faces as a wedge and force them to spread, such actionprogressively increasing as the fastener is driven home, with the resultthat each furcation or prong f is arcuately bent away from the otherprong or furcation f and to some extent back upon itself, thus firmlyanchoring in the material of the. support or foundation. The furcationsf being of stiff unhardened or untempered thin wire stock withthefurcations extending substantially parallel closely adjacent 4eachother and with their distant outer edge faces extending vertically andbeing intersected by the beveled faces f' to form cutting penetratingedges, it follows that on being driven into the support or foundationthe furcations will penetrate the same closely adjacent each other, andwill only begin to bend apart within the body of the foundationorsupport itself, the furcations ,f not being spread or pried apart, butheld close together by the material of said support adjacent saidfurcations. Consequently, these fastening means, although less than halfthe length of ordinary nails, will provide a firm and lasting attachmentfor the molding or the like and by reason of their short length theuniform attachment of the molding around sharp bends is rendered acomparatively easy operation. Where, as shown in Figure 6, the materialg to which the attachment is made isof a shallow depth, for instance awood veneer, and mounted cna metal plate or foundation h the improvedattachment devices not only spread when l driven home but the ends onmeeting the metal plate are deflected to produce an effective clinch.

In the case of metal moldings, suchv as the drip may, as shown,Abe'formed with a longitudinal channel a1 and the heads j? of theattachment devicespermanently secured therein by rolling over the lips'va2 of thev channel. Or, again, the

' said devices may bejweldedor soldered tothe molding or-thelatter'maybe perforated to re` f ceive the. attachment-deviceswith'adriven'o'r forcent so as `to/beconle permanently associated Itegrally'withfthe metal stripi'byfbeing. formed with lopposed downwardlyand outwardly beveled Q ismadefof foldedfabric, `as shown in Figures- 9.

f faces f as above-described for the reason above stated.

11n some cases where the core ofthe beading and-ljthe attachment'devicesfgare first driven through the unfinished core a3 at intervals -along.its length and the heads spot welded to a strip of 'metal e1 runninglengthwise of the core.

The formation of the core is then completed so as to enclose this stripe1 and covered with an outer covering lc of fabric or the like.

Alternatively, as represented in Figures 11 and 12 the attachmentdevices are driven at intervals vthrough the uncompleted core a3 in theform of staples f3 the projecting limbs or prongs of which aresubsequently pressed together `parallel with each other to form abifurcated shank, the loop at the closed end engaging'the material ofthe core and providing a very secure anchorage. As before, the core'isthen completed and enclosed in an outer covering k. The free ends oftheprongs are bevelled as shown so that when the spike is driven home theywill spread apart, and securely retain the beading in position.

Besides the facility with which headings and the like can be attachedwhen using attachment devices of the kind herein described the latter,as already intimated, with reference to Figure 6, have the furtheradvantage that owing to their short length but elfective form they canbe used where the material tol which the attachment is to be made is ofshallow depth and for which ordinary nails would be entirely unsuitable.
